SPECIFICATION forming part of Leal-.rs Patent No. 289,941, amanece-meer V1.1, ieee,v

Application filed Julyl 24, 1853. (No model.)

To all whom may concern:

Be it known that I, JOSEPH H. SWIFT, of Brooklyn, N ew York, have invented certain new and useful Improvements in BoX-Nailing Machines, set forth in this specification and the drawings thereof.

The invention consists in improvements relating to the construction. of the nail-feeder and the nail-driver and intervening mechanism, and the combination of the same.

Figure l is a front view of the machine; Fig. 2 is a rear view thereof. Fig. 3 is a side Figs. 4, 5, 6, 7, 8, 9, 10, and l1 are detail views of portions thereof.

In the form of construction `shown on the frame A, Fig. 11, arefour bearings, B,in which are supportedthejournals Cof the shafts DE.

On the shaft D is a driving-pulley, F, which is driven by a belt from suitable driving-power. The driving-pulley F is loose on the shaft D, and has a conical recess, G, into which is fitted av conical friction-pulley, H. The friction-pulley H has a neck, K, with a iiange, L, and is loose on the shaft D, but is held from turning thereon by a groove, M, and feather'l N; `The friction-pulley H is operated `back and forth on the shaft D into and out of the conical recess G, to fasten or unfasten the pulley` plying pressure to the foot-piece X when the pulley F is in motion, the friction-pulley H is forced into the conical recess G in the pulley F, andby friction is locked therein, and causes the shaft D to be driven. The pinion Z on the end of shaft D drivesthe cog-wheel A' on the end of shaft E and gives motion thereto.

On shaft E is a cam-wheel, C'. The camwheel C' has a cam, D', on its side.

' On the shaft U is anv arm, E', having at its upper enda roller, F', which rolls against the cam D' on the cam-wheel C'. The arm E' is adjustable by Vset-screw G.

1 Vhen the pressure is `suddenly applied to the foot-piece X, thelever P depressed, the

friction-pulley H engaged with the pulley F, -l

and-the shafts C D in motion, and the pressure suddenly removed from the foot-piece X, the roller F' operates against the cam D' on the side of the cam-wheel C' and holds the friction-pulley H engaged with the pulley F until one revolution of the cam-wheel C' is made, when the roller F' drops into a notch, H', at the `end of the cam D' and releases the frictionpulley H from the pulley F, which is then drawn back by the retracting-spring Y against the friction-brake K' on the frame A,and the motion of shaft 4D is stopped. The brake K' is adjustable by set-screws in the frame A, and may press the edge 'or back of the'friction-pulley H. As the motion of the shaft D is intermittent, depending as itdoes upon the operation of the elbow-lever P, the frictionpulley H, the rollerF, and the cam D', so the motion of shaftE is also intermittent.

On the end of shaft E is a crank, L', which has a wrist-connection, M'fwith pitman N', Fig. 8, to which it imparts intermittent motion. Pitman N' is connected by a Wrist, O', to. the segments F', and imparts' intermittent motion to them. The segments P' are fixed at their centers to the ends -of short shafts Q',

having 'bearing S' on the frame A, and cranks T' at their other ends.

To the wrists YV' of cranks T' are connected short pitmen V', which are connected at their other ends by pivot-bolts V to the cross-head X', and impart intermittent motion to it from the segments. The cross-head X', Fig. 3, has

V end grooves ,Y', and is intermittently reeiprocated in the frame A on Vfways Z'. Nailpunches A5, Fig. 4, have eccentric heads 13,

` and are slid into position and suspended in a T-groove, C5, in the lower edge of the crosshead X'. The nail-punchesA5 enter channels D5 in nail-boxes E5, and are reciprocated with the cross-head X', but are not thereby withdrawn from the nail-channels D, but remainl ing-bar, G5, and held by set-screws H5, in connection with the nail-punches A5. The nail-l boxes E-are made in two' parts, K5` L5, held The nail-boxes E have n'1ortisesF5, 'throughv which they are slid into position on a support- IAOO ` Z, Fig. 8, in position to be nailed, a slide, C

togetherl by set-screws at Mi Each of the parts K L has a recess, N, into which is placed a slide or die, O, and compressionsprings Pf. The slides or dies O have slots Q, by which they are suspended on pins B in one of the parts Ki'. They also have counterpart nail-grooves S of the forni shown, which together form nail-guides T, to he closed or opened at the lower end, Wi. The compressi on-spri n gs P keep the slides or dies Oclosed, and consequently the lower ends of the guides T5 closed, until they are forced open by the descent of the nail-punches A5. rfhe parts K. L have channels 'V,whieh -form nail-grooves 4U, into which enter nail-tubes X, Fig. 3. The nails descend through the nail-tubes X5 and the naihgrooves U into the nail-grooves S, and onto the closed end \V thereof, and rest on their points until the naitpunches A dcscend, strike the nails on their heads, and force open the slides or dies O, and drive 'the nails through the nail-boxes E into the work to be nailed to form the boxes.

The work is placed on a table, Y, undei the nail-boxes E, and againstaback plate, The table Y and the back plate, Z, are both adjustabletoy suit the work. rlhe table Y is adjustable by arms A, Fig. 2, passing through slots B in the back plate, Z, and connected with a block, C, through which passes an adj usting screw, D, supported at its lower end in a Socket, E, on the frame A, and having at its upper end a bevel-Wheel, F, connecting with a bevel-Wheel, G, on a shaft, l having a hand-wheel, K, to operate the screw D 'to raise or lower the table to suit the work under the nail-boxes E, The back plate, Z, is adjustable as the height of the pieces for the boxes against it may require. By slide-arms L, Fig. l0, in grooves Min the frame A, in the inner ends of which are eccentrics N on a shaft, O", having a hand-lever, P", to operate, the slidearms are moved in or out the nailboxes E as the thicknesses of the pieces of the work to be placed against the back plate, Z, may require. The pieces of the work against theback plate, Z, Fig. l, are held from bending or splitting by clamps Q, having V end grooves, R, to clamp the pieces. The clamps Q slide in grooves S on the frame A, formed by lugs or projections T, and are operated to hold and release the pieces of the work against the back plate, Z, by pins U in cams V in bars W, connected to projections X on the crosshead X', by which they are intermittently reciprocated.

To one side of and adjacent to the table Y isan incline, B, Fig. t), properly supported to receive the pieces of the work that are to go against the back plate, Z, and to permit them to slide forward by gravity. To slide these pieces endwise in front of the back plate,

Y sliding in grooves DS in a supporting-frame, 128,. 1sV intermittingly operated by a pin, F, and a slot, G, in an elbow-lever, H, pivoted at K to a projection, L, on the frame A, and intermittingly operated by a slot, M, and a pin, N,'fiom the cross-head X.

On the shaft O, Fig. 7, are eccentrics O, operating against swinging rods 1?, Fig. 10, pivoted at Q to projections R on the frame A, and having at theirlower ends pins S, passing through the slots B in the back plate, Z5, to bear against the pieces of the work that are in front of the back plate, Z, and limit their position with respect to the other pieces of the work to be nailed to them, so as to permit, for example, the end pieces of' boxes to stand in a little from the ends of the side pieces, to afford protection to prints or labels on the ends ofthe boxes.

To the frame A is fastened an annular plate, C7, Figs. l and 6. Across the under side of the annular plate, C7, and fastened to it, isa bar, D7, to which is pivoted centrally at N7 a perforated plate, L?, having on its under side, above the bar D7, a ratchet, F7, in which operates a weighted pawl, F7, to revolve the perforated plate L7. The pawl is operated by an elbowlever, G7, pivoted to abracket, M7, asa fulcrum to the pawl F7, and the long arm P7is slotted to receive the wrist-pin Q7 of the pitinan H", which is connected to the cross-head X, from which intermittent motion is imparted to the perforated plate L7.

On the lower side of the annular plate C is a nail-receiver, K7-a receptacle into which the nails drop from the pcrforations T7 in the perforated plate L7 through an opening in the annular plate C7, and from which nail-tubes X lead to the nail-guides T in the nailboxes E'.

To prevent the pawl F from raising the edge of the perforated plate L7, clips V7 may extend from the annular plate C7 over the edge of the perforated plate L7 or into a groove in the edge of it. The perforated plate L7 should be perforated at regular intervals adapted to the ratchet, and in rows adapted to the number of nail-punches to be used at one time in nailing the work. The nails should be placed in the perforations T7 in the perforated plate L7, by hand, point foremost. As the perforated plate L7 revolves, the rows of nails will be dropped into t-lienai1-receiverK7 and into the tubes X, and be conducted to the nail-guides T5 in the nail-boxes E in the proper position to be driven. The perforated plate L7 has projections X7 on its lower side, to give depth enough to the perforations T7 to hold the nails in a vertical position. The perforated plate L7 has a basin, Y7, to fit into the opening Z7in the annular plate C7, and the ratchet E7 is on the bottom of the basin Y7, which serves as a receptacle for the nails in bulk. rlhe annular plate C7 has an opening, V7, in front or rear of the nail-receiver K7, for the escape of misplaced nails. The perforated plate L7 isregulated in its movements by friction-brakes A, adjustable and held to the frame A by setscrews B,
